oxidative phosphorylation

Detailed explanation-1: -During oxidative phosphorylation, electrons derived from NADH and FADH2 combine with O2, and the energy released from these oxidation/ reduction reactions is used to drive the synthesis of ATP from ADP.
Detailed explanation-2: -So, the correct option is ‘ Krebs cycle’.
Detailed explanation-3: -Krebs Cycle (also known as the Citric Acid Cycle): Uses the pyruvate molecules from Glycolysis to generate 2 ATP as well as several molecules of FADH2 and NADH for the electron transport chain. Krebs Cycle takes place in the mitochondrial matrix and requires oxygen.
Detailed explanation-4: -The process that produces both NADH and FADH2 is the citric acid cycle, the second step in aerobic cellular respiration.
Detailed explanation-5: -Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria (called the electron transport chain and ATP synthase) to create ATP.
